Add the meat and cook to brown, stirring occasionally, about 5 minutes. Add the onions and cook another 3 to 5 minutes, until the onions begin to soften. Stir in the jalapeno and the garlic. Deglaze the bottom of the pan with a few tablespoons of the chipotle soaking water.,Add the cumin, coriander, beans, tomatoes, chocolate, vinegar, and one sprig of the oregano. Add the chipotle and the remainder of the soaking water. Stir to combine the ingredients thoroughly. Bring the liquid to a bare simmer and cover the pot.
